SEER is an authoritative source of information on cancer incidence and survival in the United States. SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S. population.

World (WHO 2000-2025) Standard

The World Health Organization's (WHO) new World Standard Population, described in Discussion Paper 31: Age Standardization of Rates: A New WHO Standard (PDF), was added to SEER*Stat in April 2013. Because the WHO population proportions for each age group do not sum to 100 percent, we adjusted the proportions to add precision so they sum to a round number. To use these proportions in SEER*Stat, we had to convert the values to integers. The table below summarizes the adjustments made for use in SEER*Stat.

* The Standard in SEER*Stat for the 90-94 age group needed to be increased by one so the total would sum to 1,000,000. That group was selected because it was the number closest to rounding up that did not.

The World (WHO 2000-2025) Standards database is provided for 18 and 19 age groups, as well as single ages. To derive the single ages from the 5-year age group proportions, we used the Beers "Ordinary" Formula. For more information on why we use single ages, refer to 2000
US Standard Population vs. Standard Million.
